Dic of seawater

WebOct 27, 2010 · DIC is defined as the sum of all the inorganic carbon species in solution ([DIC] = [CO 2 *] + [HCO 3 –] + [CO 3 2]). At a typical surface seawater pH near 8.1 at 25°C, CO 2 * constitutes less than 0.5% DIC. At pH 3, 99.9% of DIC is in the form of CO 2 *. Therefore, DIC can be measured by acidifying seawater to a pH below 3.0, whereupon … WebThe decomposition of macroalgal detritus (tubular and planar Ulva spp.) was studied in a microcosm under a daily light:dark cycle to simulate the decomposition on intertidal sediment. The consequences of bloom decay were evaluated in the bulk water phase and in the sediment. Inorganic nutrients (NO3 - , NO2 - , NH4 + , PO4 3- and SiO3 2- ), …
